WAGON-BOX ELEVA TOR AND DUMPER.

SPECIFICATION forming part of Letters Patent No. 732,107, dated June 30, 1903. Application filed January 27, 1903. Serial No. 140,725- (No model- RosLAv FOLDA, residing at Rogers, in the countyof Colfax and State of Nebraska, have invented certain useful Improvements in Wagon-Box Elevators and Dumpers; and we do hereby declare that the following is a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

This invention relates to a new and useful portable wagon-box elevator and dumper.

The aim of our invention is to provide a portable frame so constructed that the same may be placed adjacent a corn-crib or elevator-chute, so that the wagon-box containing the grain may be raised upward a suitable height and then be tilted to discharge the load, as will be described more fully hereinafter and finally pointed out in the claim.

Figure 1 shows an elevation of a dumper embodying our invention. Fig. 2 shows a rear end view disclosing the method of securing the tail-gate, while Fig. 3 shows a broken detail disclosing the arrangement of the pin used in retaining the endgate.

In carrying out the aim of our invention we use two sills 1 and 13, which are connected by two horizontal frame members 15, and these frame members are connected by a transverse brace 16 and two cross-braces 14, as shown. Extending upward from the sill 13 are two similar supporting-posts 17 and a central supporting-post 12, while extending from the sill 1 are two similar supportingposts B, inclined slightly inward or toward the posts 17, these two posts B being much longer than the posts 12 and 17 and are strengthened by the cross-braces B, the transverse brace b, and the bracket 40, near the upper end. Extending upward from the posts 17, which incline toward one another A-shaped, is the boom A, which above is secured between the posts B, which are also united A-sbaped, the boom A projecting a suitable distance beyond the inclined posts B, as shown. This boom above rests upon the bracket 40 and a cleat 39, while the rear verticallysupporting post 12 supports the boom at the lower end.

To form a rigid structure, the boom A is secured to the inclining posts B by means of suitable braces 19, 20, and 21, as shown.

Extending upward from the boom A at the point where the same is united to the inclining posts Bis a standard 23, over which passes the stay-rod 24, suitably secured to the boom to brace the same, as shown.

At a suitable point we secure to the inclined posts B by means of suitable pins 35 a tilting frame comprising two counterpart side members 36 and frame members 36, and the transverse brace members 37 to form a tilting frame. Extending from the sides of'these tilting-frame members 36 is a double-ended strand 38, which below is suitably secured, so that this tilting frame may be held at any suitable angle.

Secured to the forward end of the boom A by means of a staple 10 is a sheave 9, provided with an ear 8, from which extends the strand 5, provided with the sheave I), having a hook a, this strand next passing over the sheave 9, thence over a sheave 6, secured by means of the ring 7,and then extending downward and passing over a sheave 4, as shown.

This portable wagon box elevator and dumper is adapted to be placed adjacent a crib Z-for instance, asshowu in Fig. 1the instrumentalities being so arranged that the tilting frame will be a suitable distance above the top of the crib. Now should it be desired to empty the wagon-box D, provided with the running-gear X, the operation would be as follows: The wagon-box D would be provided with a suitable clamp, comprising the bottom cleat 27 and the top cleat 25, which are united by means of suitable nut-provided bolts 26, the upper or top cleat being provided with a suitable eyebolt a, so that the same may be engaged by the book a. The tail-gate 34. of the wagon-box D is next secured by means of the pivot-pins c in such a manner that the tail-gate 34 will be hinged above orat its upper end, as shown in the drawings. Passing through the rear transverse strengtheningbar 27 of the wagon-box is a suitable pin 33, adapted to secure the lower end of the tailgate 34, as shown in Figs. 2 and 3. The operator would next secure to any suitable point of the wagonbox D the eye 30 and fasten thereto the end of a strand 31, the remaining end of the strand being provided with a hook 32, which can be hooked into the pin 33, the strand 31 then being made to pass over a suitable hook 30 or over the hook at, so that when one end of the strand 31 is pulled the pin 33 will be released. The draft-animals which had been used in drawing the vehicle would next be secured to the end of the strand 5 and be drawn forward to raise the wagon-box D a sufficient height so that the wagon-box would come above the upper edge of the tilting frame 36. The strand 31 would then be used to turn the wagon-box at right angles to the tilting frame, when the horses would be backed, permitting the lowering of the wagonbox, so that one end engaged the tilting frame, as shown in Fig. 1. As soon as the wagon-box had been sufficiently tilt'il the operator would jerk the strand 31 to draw out the pin 33 permitting the tail-gate to fly open, and so empty the load; Occasionally the grain clings to the wagon-box, and then the operator grasps the strand 38, soon red to thetiltingframe 36,andvjerks thetiltingframe upward and permitting it again to drop forward a suitable distance to shake the wagonhox, and so empty it of any clinging material. After the load is emptied the operator by means of the'strand 31 guides the wagon-box properly, so that it will again come upon the running-gear as the draft-animals are backed in lowering the wagon-box. By this means at the loss of but little time an entire wagonload of material may be emptied.

Having thus described our said invention, what we claim as new, and desire to secure by United States Letters Patent, is-

A wagon-box elevator and dumper, comprising the combination of the following instrumentalities,to wit: two forward inwardlyinclined posts, two rear stub-posts, sills connecting said posts below, said posts being secured A-shaped, a boom extending from said stub-posts and secured to said inclined posts, said boom projecting beyond said inclined posts, a sheave at the highest end of said boom, a sheave secured to one of said inclined posts, a hook-provided strand passing over said sheaves, a tilting frame secured to said inclined forward posts, a strand extending from said inclined frame to adjustably hold said inclined frame, a clamp adapted to encompass a suitable wagon-box, a wagon-box removably held between said clamp, a tailgate within said wagon-box pivotally secured at its upper end, a pin secured to said tailgate, and a strand secured to saidipin and to said wagon-box, to release saidpin and guide said wagon-box, all arranged substantially as and for the purpose set forth.

In testimony whereof we affix our signatures in presence of two witnesses.
